This tutorial gives an introduction to GUI programming using the Qt toolkit, Ruby, and qt4-qtruby. It is simply a port of Trolltech's fine Qt Tutorial. Therefore, most of the text after this paragraph comes straight from their tutorial. I have modified it as necessary to make it make sense with the Ruby bindings, and have rearranged or rewritten a few parts to make them (I hope) a bit clearer.
Right now this tutorial is hosted on my site. I am going to be bringing it over here over the next week or so.
